Left screed control box
Check the mat thickness at several places across the mat. Make any adjustments to the controls that are needed. This switch controls the thickness of the mat on the left side of the machine. In order to increase the thickness of the material, move the switch upward. In order to decrease the thickness of the material, move the switch downward. Note: Do not adjust the controls too often. Allow at least five lengths of the tow arm. This allows the adjustment to take effect before you make another adjustment. Note: When you release the switch, the switch will return to the center position. When the switch is in the center position, the screed will remain in the last selected position.Note: Use the right screed control box in order to change the thickness of the mat on the right side of the machine.Setting the Paver Speed
After the paver has been set up and the paver has been adjusted, one of the most important fundamental concepts of smooth paving is maintaining a constant paving speed. In most cases, the machine can pave smoothly at any speed. The paving speed must match the delivery of mix to the job site. Maintaining a constant speed is crucial for a smooth mat.The best paving speed is slightly faster than the delivery of the asphalt. Paving slightly faster than the delivery of the asphalt allows time for tasks such as raking joint surfaces.If the paving speed is changed significantly, the screed's height will change and the mat's smoothness will suffer. Also, if paving speed changes, the demands on the feeder system change. You must adjust the feeder system's controls in order to match the new settings.For quality results, always follow the basic concepts for setup and keep the operation consistent. Ending a Mat
Several methods are used in order to obtain a good vertical edge at the end of a mat. The methods will allow a compactor to move on the mat and off the mat.

One method of ending a mat uses a piece of paper (14) about 914 mm (3 ft) wide. The paper should be a little longer than the width of the mat.The paver is run until all of the material in the hopper is used. The conveyors and the vibrators are stopped when the hopper is empty. The screed is lifted and the paver is moved away from the mat. Rake the material evenly across the width of mat (16) in order to form an opening for the paper. The paper is laid across the width of the mat in the opening. Material (15) is raked onto the paper. The material is raked to the same depth as the mat that was laid.A layer of dirt or other material can be used instead of the paper in order to achieve the same results.

Another method of ending a mat uses board (18) that is the same thickness as compacted mat (19). An opening for the board
